From e2724e9d969294879936daf7833d4adda26c8efc Mon Sep 17 00:00:00 2001 From: Jeremy Compostella Date: Wed, 11 May 2016 17:23:34 +0200 Subject: [PATCH] x86/tsc: Add missing Cherrytrail frequency to the table Intel Cherrytrail is based on Airmont core so MSR_FSB_FREQ[2:0] = 4 means that the CPU reference clock runs at 80MHz. Add this missing frequency to the table.
